no, for several reasons:
1) ping is bad (because it actually requires CAP_NET_RAW),
and there is tracepath, which works inside a vserver
without requiring this capability ...
2) iptables need a virtualized network stack, which isn't
done yet for linux-vserver, freevps support that IIRC
3) there are some options for /proc/mounts
a) you can remove the entire /proc/mounts
(most tools work with this setup)
b) you can enable a 'fake' /proc/mounts
c) wait for the next few releases, they will
probably allow you to modify the visibility
of /proc entries in general ...
